Description
本考案は、放熱装置に関するもので、特に放熱フィンの熱伝導効率を有効に高め、放熱フィンの空気対流スピードを高める放熱装置に係わる。 The present invention relates to a heat radiating device, and more particularly to a heat radiating device that effectively increases the heat conduction efficiency of the radiating fins and increases the air convection speed of the radiating fins.
現在発光ダイオードを照明に使用する場合、相当数の発光ダイオードを同時に使用することで、やっと伝統的なフィラメント電球もしくは蛍光灯管の輝度効果を得ることができる。これらの発光ダイオードは、特定の排列方式で基板上に設置する。一般の基板の多くはプリント回路板(PCB)で、プリント回路板の材料特性は、発光ダイオード部品と放熱台の間の熱伝導に敵していない。 If light emitting diodes are currently used for illumination, the luminance effect of a traditional filament bulb or fluorescent lamp tube can be finally obtained by using a considerable number of light emitting diodes simultaneously. These light emitting diodes are installed on the substrate by a specific arrangement method. Many of the common boards are printed circuit boards (PCBs), and the material properties of the printed circuit boards do not match the heat conduction between the light emitting diode components and the heat sink.
そのため、一般に発光ダイオードを使用した照明具は、一定時間使用すると、その基板上の発光ダイオードは熱を持つ現象が発生し、発光ダイオードの照度を保つことが出来ないだけでなく、発光ダイオード部品の使用寿命を下げてしまう。そのため、発光ダイオードを使用する照明具には通常、基板上もしくは照明具外部に放熱フィンが設置され、放熱フィンの設計として空気対流方式により放熱効果を高める。 Therefore, in general, when a lighting device using a light emitting diode is used for a certain period of time, the light emitting diode on the substrate is heated, and not only can the illuminance of the light emitting diode be maintained, but also the light emitting diode components. It will shorten the service life. For this reason, a radiating tool using a light emitting diode is usually provided with a radiation fin on the substrate or outside the luminaire, and the heat radiation effect is enhanced by an air convection method as a design of the radiation fin.
解決しようとする問題点として、放熱フィンは主に空気対流によって放熱効果を達成する。現在、単結晶固相の金属材で製造した放熱フィンは、その熱伝導係数がほぼ固定値から見て(銅及びアルミニウムの係数値は、それぞれ約３９３W/mk 及び２３８W/mkである)、単純に放熱フィンによって空気が対流し、放熱効果を得ているだけであるため、発光ダイオード照明具のチップが過熱してしまう課題を解決できないでいる。 As a problem to be solved, the heat radiation fin achieves a heat radiation effect mainly by air convection. At present, the heat dissipation coefficient of a heat sink made of a single-crystal solid phase metal material has a substantially constant thermal conductivity coefficient (coefficient values of copper and aluminum are about 393 W / mk and 238 W / mk, respectively). However, the problem is that the chip of the light-emitting diode illuminator is overheated because air is convected by the radiating fins and only a heat radiating effect is obtained.
本考案は、各組の放熱フィンユニット基部に少なくとも一剛性導熱材を設置して各放熱フィンの間に伸びる。他に少なくとも一撓み性超電導体は各放熱フィンの間に差し込む。該少なくとも一撓み性超電導体の一端は、該少なくとも一剛性導熱材と相互に溶接する。そのうち、撓み性超電導体は、撓み性管体内部に作動流体を充填し、温度変化不変の状況に於いて大量に熱エネルギーを伝導する効果を形成し、放熱フィンの熱伝導効率を高めることを最も主要な特徴とする。 In the present invention, at least one rigid heat conducting material is installed at the base of each set of radiating fin units and extends between the radiating fins. In addition, at least one flexible superconductor is inserted between each radiation fin. One end of the at least one flexible superconductor is welded to the at least one rigid heat conducting material. Among them, the flexible superconductor fills the inside of the flexible tube with a working fluid, and forms an effect of conducting a large amount of heat energy in a state where the temperature does not change, thereby improving the heat conduction efficiency of the radiating fin. The most important feature.
本考案の放熱装置は、放熱フィンの熱伝導効率を高め、放熱フィン空気対流スピードを上げるという利点がある。 The heat dissipating device of the present invention has the advantages of increasing the heat conduction efficiency of the heat dissipating fins and increasing the air fin convection speed.
放熱フィンの熱伝導効率を高め、放熱フィン空気対流スピードを上げる放熱装置を提供することを本考案の主な目的とする。 The main object of the present invention is to provide a heat radiating device that increases the heat conduction efficiency of the radiating fin and increases the air convection speed of the radiating fin.
上述の目的を達成するため、本考案の放熱装置は、各組の放熱フィンユニット基部に少なくとも一剛性導熱材を設置して各放熱フィンの間に伸びる。他に少なくとも一撓み性超電導体は各放熱フィンの間に差し込み、該少なくとも一撓み性超電導体の一端は該少なくとも一剛性導熱材と相互に溶接し、更に各放熱フィンの相対する位置には、少なくとも一通気口を設置する。 In order to achieve the above-described object, the heat dissipating device of the present invention extends between the heat dissipating fins by installing at least one rigid heat conducting material on the base of each heat dissipating fin unit. In addition, at least one flexible superconductor is inserted between the heat radiating fins, one end of the at least one flexible superconductor is welded to the at least one rigid heat conducting material, and at the opposite positions of the heat radiating fins, Install at least one vent.
そのうち、撓み性超電導体は、撓み性管体の内部に作動流体を充填し、作動流体の相変化の過程で、熱エネルギーを吸收、放出し、連続的に熱を伝導し、撓み性超電導体の温度不変の状況に於いて、スピーディに熱エネルギーを伝導し、放熱フィンの熱伝導効率を高める。更に各通気口の作用によって、放熱フィンの空気対流スピードを相対して高める。 Among them, a flexible superconductor fills the inside of a flexible tube with a working fluid, absorbs and releases heat energy in the process of phase change of the working fluid, and conducts heat continuously. In this situation, the heat energy is quickly conducted and the heat conduction efficiency of the radiating fin is increased. Furthermore, the air convection speed of the radiation fin is relatively increased by the action of each vent.
図１及び図２に示すとおり、本考案の放熱装置は、少なくとも一組の放熱フィンユニット１１、少なくとも一剛性導熱材１２及び少なくとも一撓み性超電導体１３を含む。そのうち、 As shown in FIGS. 1 and 2, the heat dissipating device of the present invention includes at least one set of heat dissipating fin units 11, at least one rigid heat conducting material 12, and at least one flexible superconductor 13.

In addition, at least one perforation 113 is installed on one piece of each radiating fin 111 and the at least one flexible superconductor 13 is inserted and installed, and at least one vent 114 is provided on one piece of each radiating fin 111.

該少なくとも一剛性導熱材１２は、各組放熱フィンユニット１１基部に相対して設置し、各放熱フィン１１１の片体の間に伸びる。それは各放熱フィン１１１の嵌合凹口１１２内に嵌入する銅製方形桿状構造体で、桿体上には予め複数の定位点１２１を設置して、各放熱フィン１１１を定位するのに用いる。 The at least one rigid heat conducting material 12 is installed so as to be opposed to the base portion of each set heat radiation fin unit 11 and extends between the pieces of each heat radiation fin 111. It is a copper rectangular bowl-like structure that fits into the fitting recess 112 of each radiating fin 111, and a plurality of localization points 121 are installed in advance on the pod and used to localize each radiating fin 111.
該少なくとも一撓み性超電導体１３は、各放熱フィン１１１の片体の間に差し込み、その一端は該少なくとも一剛性導熱材１２と相互に溶接する。実施時、該少なくとも一撓み性超電導体１３は、撓み性管体１３１を備え、該撓み性管体１３１内部には作動流体１３２が充填され、該撓み性管体１３１は、各放熱フィン１１１の穿孔１１３に差し込み、該撓み性管体１３１の一端は該少なくとも一剛性導熱材１２と溶接される。 The at least one flexible superconductor 13 is inserted between one piece of each heat radiation fin 111, and one end thereof is welded to the at least one rigid heat conductive material 12. In implementation, the at least one flexible superconductor 13 includes a flexible tube 131, and the flexible tube 131 is filled with a working fluid 132. One end of the flexible tube 131 is welded to the at least one rigid heat conductive material 12 by being inserted into the perforation 113.
他に、図３及び図４に示すとおり、放熱装置全体は、更に導熱固定台１４を含む。該導熱固定台１４の最上面には、少なくとも一定位凹部１４１を設置し、そこに該少なくとも一組の放熱フィンユニット１１を嵌入し、放熱装置全体の構造強度を高め、該導熱固定台１４によって、使用對象(図に示すのは発光ダイオード照明具２０)と熱源を接触させる。 In addition, as shown in FIGS. 3 and 4, the entire heat dissipating device further includes a heat conducting fixing base 14. On the uppermost surface of the heat-conducting fixing base 14, at least a certain degree of concave portion 141 is installed, and at least one set of the radiating fin units 11 is inserted therein, thereby increasing the structural strength of the entire heat radiating device. The object to be used (shown in the figure is a light-emitting diode illuminator 20) is brought into contact with a heat source.
放熱装置全体を使用する時、各組の放熱フィンユニット１１が発生させた空気対流によって放熱効果を達成する。更に各組の放熱フィンユニット１１の撓み性超電導体１３内部の作動流体１３２の相変化過程において、大量の熱循環が吸收と放出で連続性の熱伝導を行い、撓み性超電導体１３の温度がほぼ変わらずに維持される状況に於いて、大量の熱エネルギーをスピーディに伝導し、放熱フィン１１１の熱伝導効率を高める。更に各通気口１１４により、放熱フィン１１１の空気対流スピードを相対して高める。 When using the entire heat dissipating device, the heat dissipating effect is achieved by the air convection generated by each pair of heat dissipating fin units 11. Furthermore, in the phase change process of the working fluid 132 inside the flexible superconductor 13 of each set of the radiating fin units 11, a large amount of heat circulation performs continuous heat conduction by absorption and release, and the temperature of the flexible superconductor 13 is increased. In a situation where the temperature is maintained almost unchanged, a large amount of heat energy is conducted quickly, and the heat conduction efficiency of the radiating fin 111 is increased. Furthermore, the air convection speed of the heat radiating fins 111 is relatively increased by the vent holes 114.
